Primary Examiner0thell M. Simpson [57] ABSTRACT A pair of pliers for depressing condenser springs, the device comprising a pair of levers attached pivotly free at their centers, one ends of the levers forming jaws between which a condenser can be fitted, the tool further including a sparkplug guagel and a point guagel as well as an interchangeable socket head, an open wrench and screwdriver.

2 Claims, 4 Drawing Figures CONDENSOR SPRING DEPRESSOR PLIERS This invention relates generally to specialized pliers. More specifically the present invention relates to pliers used for servicing specific engines.

A principal object of the present invention is to provide a pair of pliers which is especially suitable for servicing a Briggs and Stratton engines.

Another object of the present invention is to provide a pair of pliers comprising a hand tool that can be conveniently manipulated for performing various different services in the maintenance of a Briggs & Stratton engme.

Other objects of the present invention are to provide a pair of pliers which are simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a side elevation view of the present invention,

FIG. 2 is a side elevation view of a point arm mechanism which is installed or removed according to one use of the invention FIG. 3 is a fragmentary view in the direction of 33 of FIG. 1, and

FIG. 4 is a fragmentary view in the direction of 44 of FIG. 1.

Referring now to the drawing in detail, the reference numeral represents a pair of pliers especially suitable for use on Briggs & Stratton engines according to the present invention wherein there is an assembly comprised of a pair of levers 11 and 12 which are attached pivotly free together along an intermediate portion there of by means of a screw 13.

One of the levers 11 is provided with a jaw 14 at one end thereof which which co-acts with a jaw 15 formed on the other lever 12. The jaw 14 forms a seat for one end of a condenser 16 while the other jaw 15 is provided with an opening 17 into which is fitted one end 18 of the condenser 16 so that a compression coil spring 19 can be depressed.

A slot 20 serves to receive a pin 21, as shown in FIG. 1 of the drawing.

The opposite ends of the levers I1 and 12 form handles which may be grasped within a persons hand and compressed so as to depress the spring 19 on the condenser 16.

A generally U-shaped lock bar 22 pivotable at one end about a block 23 serves to secure the handles in a gripped position so it can be retained in a holding position while a person removes his hand therefrom.

One end of the lock bar 22 forms a 0.025 spark plug guage 24 as shown.

On the handle end of the lever 11 there is provided an open wrench 25 adjacent to which there is secured pivotly free a feeler guage 26 secured by means of a singular screw 27.

On the end of the other lever handle there is removably fitted a socket head 28 having a socket opening 29 for turning bolt heads or bolt nuts.

The member 28 is interchangeably with other sockets of different sizes, and is fitted upon the end of the lever handle by means ofa detent or set screw 30.

The end of the jaw 14 is provided with a screwdriver 31 while the other jaw 15 has a retractable push-andpull arm 32 secured thereto by fastening means received in slots 33 of the arm.

It is to be noted that the screwdriver is used for loosening a cover and condenser clamp. The outer end of the push-and-pull arm is used to spread the spring (see FIG. 2) when removing and installing ignition point arm and spring.

The open wrench 25 is of one-quarter size. The feeler guage 26 is of 0.020 thickness and is used to set the point gap. The socket 29 may be of one-quarter inch or interchangeably with other sizes.

In operative use, the flywheel cover is removed. The screen on the flywheel is then removed either by use of the socket, the screwdriver or the open wrench.

The push-and-pull member 32 is then engaged with the end of the spring and the opposite side of jaw 14 is engaged with the spring binding post. The jaws are opened to expand the spring and the point arm and spring are removed. The slotted jaw 15 is then fitted over the condenser and so to depress the condenser spring coil which is then removed. The condenser clamp screw is loosened to remove the condenser and install a new condenser snuggily by use of the clamp screw.

The condenser arm is then installed and the screw is tightened. The engine is turned so to plunge out to its high points. Now set the point gap by using the feeler guage 26. If it is too close of a gap, then use the screwdriver for adjustment.

The adjustment is then secured after which the condenser is installed. Flywheel cover and flywheel are thus enclosed by using the spark plug guage 24 the spark plug gap is now set.

The plug is installed and the engine is started.

What I now claim is:

1. In a pair of pliers especially suitable for use on Briggs & Stratton engines, the combination of a pair of levers which are attached pivotally free together by means of a screw extending through intermediate portions of said levers, one end of said levers forming cooperative handles for being grasped in a persons hand, the opposite ends of said levers comprising jaws between which a condenser can be fitted so to depress the condenser spring, the first of said jaws comprising a seat against which the end of said condenser is positioned, the opposite of said jaws being provided with an opening into which the terminal post of said condenser is fitted, said opposite jaw including a slot receiving a transverse pin, said first jaw being provided with a screwdriver formed on the end thereof, one of said handles being provided with an open wrench near which there is secured pivotally free a feeler gauge, the end of the other said handle having a removable socket head securable thereto, said socket head having a socket adaptable for turning a bolt head or bolt nut, and an arm secured upon the outer side of one of said jaws, said arm having means for engaging a hooked end of a spring acting on an ignition point arm to release the spring force acting on the point arm.

2. The combination as set forth in claim 1, wherein a lock bar is attached pivotally free to one of said handles, the opposite end of said lock bar having means attachable to the other of said handles so to retain said handles in a closed position, and the terminal end of said bar forming a spark plug gauge.
